Erythronium flavum Sm.

Erythronium americanum (Trout lily, Yellow trout lily, Yellow dogtooth violet) is a North American species of herbaceous flowering plant in the lily family.[1][2]

The range is from Labrador south to Georgia, west to Mississippi, and north to Minnesota.[3][4] Trout lilies grow in colonies that can be up to 300 years old.[5][1]


The common name "Trout lily" refers to the appearance of its gray-green leaves mottled with brown or gray, which allegedly resemble the coloring of brook trout.[5][6]

It blooms in early spring with nodding one-inch yellow flowers, the petals (3) and petal-like sepals (3) recurved upward. Each plant sends up a single flower stem with a pair of leaves.[3][7][6]
